Run only a specific test?

[Jason Hihn]

In Test Driven Development, you write the tests first.

And since I am writing code for node.js, I would like to write the backend function (without the route handler) and test it. I was hoping then that I could use jasmine to be an archive of these functions. However, I wish only to run a specific function (test) at a time.

given:

 describe("A" function () { it("test1", function ()...)} )};

if I could run `jasmine A/test1` then that would be awesome because I could use the test harness as part of my development process. The only thing we would be missing is the req, resp and variable marshaling, which is pretty trivial. We could then get that via a actual HTTP request, but for engineering purposes I'm not conserned.

So is there a way to, given a complete test suite, invoke only a specific test? I know about xdescribe() and xit(), but I don't want to have to modify the test suite to test a specific function. 

Thanks

I believe you are looking for 'fit' and 'fdescribe.' They will focus Jasmine on a given spec/ suite.

Does it cause the whole test suite to return a failing state, to prevent you from forgetting to unfocus when done? In the absence of using a specific IDE/tool that supports running a single test, this is a nice solution. 

[Greg Cobb]

They do not currently fail the build, but that seems like a reasonable feature request.

Also, if you are building your own test harness, you may be able to use Env.specFilter to focus on a specific spec/ suite. This is what the HTMLReporter uses to focus on a test when you click on it.

[Gregg Van Hove]

If you're using the jasmine npm, there is a `--filter` option coming in the next release that will let you filter by full description of specs and suites. This is on master if you want to try it out.

I don't see how this is supposed to work. I read the brief documentation. It looks like I need to re-write the test in a f* block?

This sounds like what I want. Where is it documented so that I know how to try it?

Thanks!

You can use iit() for specific test and ddescribe() for specific test suite

[Greg Cobb]

'iit' and 'ddescribe' are not part of core jasmine. I believe most extensions of Jasmine using this syntax have moved to 'fit' and 'fdescribe'.

[Jason Hihn]

I'm bumpting this since I was not able to find documentation on this feature. I assume it should be available in edge?

[Greg Cobb]

Here is the PR that implemented the feature: https://github.com/jasmine/jasmine-npm/pull/35.  This should be added to the docs before 2.3 is released.
